Hard disk problems - Hard ones :))

Hi there.

I am writing a partition manager that handles FATxx file systems. As the saying goes, I am stuck with my head in the sand :)). I have difficulty with all the LBA stuff. Any links/answers/code snippets regarding the following questions will be GREATLY appreciated. Thanks a lot in advance...

Here goes... * Accessing cylinders above the 1023 mark (8GB limit) * Retrieving disk parameters (I would like to write a mini disk driver too, hence this one) * Logical/Physical head difference (no code on this one, just what the hell this is)

Thanks again. <yatam>

Hello!

You seem to need the Int 13h extensions. You may look them up in Ralf Browns famous interrupt list.
